Multi-standard silicon IP PHY from Semtech

Semtech Corp. has rolled out what it describes as a multi-standard silicon IP (SiIP) PHY that supports the latest standards for high-speed wireline and wireless networks. The SBMULTR2T2812GSiIP PHY is silicon-proven and was developed by Semtech's Snowbush IP Group, which is focused on designing high-speed serial interface IP, indicated the firm.

The platform supports JESD204B (JEDEC Standard), Common Public Radio Interface (CPRI) and open base station architectural initiative (OBSAI). The IP also supports 10GBase-KR, CEI-11G and PCI-Express 3.0.

According to Semtech, the SBMULTR2T2812G SiIP PHY is tuned to meet the performance of each standard through a programmable profile that sets a set of registers that control the operation of the PHY. The programmable register set controls key electrical operations and allows for post-silicon corrections to adjust to different operating environments. The PHY is available in dual- and quad-lane versions, and supports advanced channel equalisation and adaptation circuitry to optimise performance while using minimal power at each data rate and in the smallest silicon area.

The Semtech-Snowbush SBMULTR2T2812G SiIP PHY supports the three major enhancements in JESDB, a 12.5Gb/s data rate, deterministic latency and harmonic clocking. These features differentiate JESDB from JESDA. The physical interface specification is compliant with the OIF Common Electrical Interface (CEI) 6G-SR at 6.25Gb/s and CEI-11G-SR at 12.5Gb/s.

The SiIP PHY supports the physical layer data rates of CPRI, is an industry organisation cooperating to define an open and public specification for the key internal interfaces of radio base stations between the radio equipment control (REC) and the radio equipment (RE). The data-rate and electrical performance requirements for the physical layer for CPRI are programmable in the multi-standard PHY.

The SBMULTR2T28HPM12G SiIP PHY can be programmed to handle the OIF layer 1 data rates of OBSAI. OBSAI was established so that base station companies can work together to define open standards for base station internal architecture and key interfaces. The Semtech-Snowbush IP PHY supports the data rates of OBSAI Reference Point 3 (RP3), version 4.2, Type 1 through Type 5.
